Arbor Day is observed in Niger every August 3, coinciding with the country's Independence Day, which is a major public holiday. This day is significant for Nigerians as they plant trees to combat environmental issues, particularly desertification, which is a critical problem affecting the nation. The northern part of Niger is increasingly covered by expanding deserts, prompting a government program for forest restoration that has been in place since 1975. On Arbor Day, every Nigerian is encouraged to plant a tree, reinforcing their responsibility for the land they inhabit. This celebration not only addresses ecological concerns but also marks the establishment of the Republic of Niger.
